Perform the following checks: 1. Engage the brake pedal lock [when the brake pedal is fully depressed, and the linkage is properly adjusted, the speed control lever will automatically move to the neutral ("N”) position]. If the unit can be moved forward or rearward, the brake force must be increased. 2. Release the brake pedal lock. If the unit cannot be moved forward or rearward, the brake force must be decreased. Refer to the following instructions to increase or decrease brake force. To increase the brake force, refer to Figure 18 and proceed as follows: 1. Place the tractor on a level surface, with the brake pedal lock disengaged. 2. While working from the rear of the tractor, turn the nut located on the end of the brake rod, clockwise one full turn at a time, until correct adjustment is achieved. Recheck the adjustment making certain correct adjustment is reached before operating the tractor. If the tractor can still be pushed with the brake pedal locked and dump valve engaged, see your authorized Cub Cadet Dealer. 16 while working from rear of tractor with unit off, proceed as follows: 1. If the tractor creeps forward, loosen the jam nut and turn the hex on the control assembly counterclockwise until tractor creep is stopped. When correct adjustment is achieved, retighten jam nut. 2. If the tractor creeps rearward, loosen jam nut and turn the hex on the control assembly clockwise until tractor creep is stopped. When correct adjustment is achieved, retighten jam nut. NOTE If condition is not corrected after performing the above steps, see your authorized Cub Cadet Dealer for service. Figure 18 1. 2. Nut Brake Rod To decrease brake force, refer to Figure 18 and proceed as follows: 1. While working from the rear of the tractor, turn the nut located on the end of the brake rod, counterclockwise one full turn at a time, until correct adjustment is achieved. Recheck the adjustment, making certain correct adjustment is reached before operating the tractor. Following this adjustment, release the brake pedal lock and engage the dump valve. If the tractor still cannot be pushed, see your authorized Cub Cadet Dealer. HYDROSTATIC CONTROLS AND ADJUSTMENT (1320 Tractor) A CAUTION On the 1320 model tractors, the speed control lever will automatically return to neutral when the brake pedal is pressed all the way down, and the linkage is properly adjusted. If this action fails to occur, contact your authorized Cub Cadet Dealer for immediate service. The following adjustment may be necessary for the hydrostatic adjustment rod if the tractor creeps forward or rearward while the speed control lever is in the neutral fN") position. Refer to Figure 19 and Figure 19 1. Jam Nut 2. Control Assembly PIVOT BAR ADJUSTMENT BOLTS CAUTION A The tractor must be checked every 50 hours of tractor operation for play between the front axle and the pivot bar adjustment bolts. Both adjustment bolt heads must fit against the front axle. If play is discovered, the pivot bar adjustment bolts must be adjusted. If play is discovered between the front axle and the pivot bar adjustment bolt heads, adjust both bolts as follows: (Refer to Figure 20.) 1. Loosen jam nut 3 to 4 turns or as required. 17 Figure 20 1. Jam Nut 2. Pivot Bar Adjustment Bolts 3. Front Axle 2. Turn pivot bar adjustment bolt counterclockwise until it hits against the front axle. 3. Tighten jam nut. 4. Repeat the above steps for the other pivot bar adjustment bolt. NOTE Tie rod has a bend in the center for clearance of castle nut on pivot bar. Bend must remain down as shown in Figure 22. WHEEL ALIGNMENT The front wheels should toe-in approximately 1/8 inch. Measure the distances A and B on the front wheels. (Refer to Figure 21.) NOTE Dimension B should be approximately 1/8 inch less than dimension A. TURNING RADIUS (1/8” LESS THAN A) Figure 21 FRONT WHEEL ADJUSTMENTS To adjust the toe-in remove one ball joint, loosen lock nuts *'C" at the ball joint and turn the tie rod ball joint in or out as required. (Refer to Figure 22.) A CAUTION Be sure all parts are tightened after completing the following adjustment. The front wheels should have an equal angle for left and right turns. If adjustment is necessary, remove ball joint and loosen lock nut "D." (Refer to Figure 22.) Turn the drag link ball joint clockwise or counterclockwise as required.
